An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-18702 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- quokka (PyPI): affected all versions; no fix listed\n- quokka (PyPI): affected all versions up to 0.4.0; no fix listed\n- quokka (PyPI): affected all versions up to 0.4.0; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-18702/ (Markdown: https://insights.sbomify.com/CVE-2020-18702/index.md)","id":"CVE-2020-18702","markdown":"https://insights.sbomify.com/CVE-2020-18702/index.md","name":"CVE-2020-18702","record":{"aliases":["GHSA-5m69-3chg-6f8m","PYSEC-2021-143"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Quokka CMS","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via XSS in the Quokka CMS admin panel's username parameter.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"quokka","vendor":"quokka_project"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross Site Scripting (XSS) in Quokka v0.4.0 allows remote attackers to execute arbitrary code via the 'Username' parameter in the component 'quokka/admin/actions.py'.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross Site Scripting (XSS) in Quokka","id":"CVE-2020-18702","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":3,"n_references":1,"next":{"headline":"Improper Restriction of XML External Entity Reference in Quokka","id":"CVE-2020-18703"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"quokka","purl":"pkg:pypi/quokka","source":"PYSEC-2021-143"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"quokka","purl":null,"source":"GHSA-5m69-3chg-6f8m"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"quokka","purl":"pkg:pypi/quokka","source":"GHSA-5m69-3chg-6f8m"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2020-18701"},"products":["n/a"],"published":"2021-08-16","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Quokka","id":"CVE-2020-18703","kev_date_added":null,"published":"2021-08-16"},{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Quokka","id":"CVE-2020-18705","kev_date_added":null,"published":"2021-08-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via XSS in the Quokka CMS admin panel's username parameter.","url":"https://insights.sbomify.com/CVE-2020-18702/"}
